I’ve had no luck using books, etc. for info on these. Could tray 1 really be sterling? Wendell? My Brother gave it to me from a flea market over 30 years ago. The second mark (American?) is from a thrift store tray I bought for $7 as it has my Sister’s married initial and was in good shape. Thank you very much for your help.
The tray most likely bears pseudo-hallmarks. However, its shape and design bear a striking resemblance to products by International Silver or the Polish firm Fraget.
